include "jsoncons/json.hpp" Am I doing something wrong?

Can you please share the command you are running to configure CMake?

Which JSON library are you intending to use?

[enriavil1]

I am intending to use nlohmann for my json library. I am just using cmake --build . I am trying to add jwt-cpp with the default options

[prince-chrismc]

Hmm 🤔 which file is complaining about the missing header?

If the library is not found, it should not be build https://github.com/Thalhammer/jwt-cpp/blob/master/example/traits/CMakeLists.txt#L8-L9

On mobile but I don't see a test for default options 🙈

[enriavil1]

I meant I added this as a submodule and I am building the whole thing with all jwt-cpp default settings at the top cmake file. (by the way I am new to using cmake, so I might be doing something wrong) I added the jwt-cpp as a submodule and added it into my top cmake file like so. add_subdirectory(jwt-cpp) target_include_directories(silkrpc PUBLIC ${CMAKE_SOURCE_DIR} ${CMAKE_SOURCE_DIR}/jwt-cpp/include) target_link_libraries(silkrpc jwt-cpp absl::flat_hash_map absl::flat_hash_set absl::btree intx::intx gRPC::grpc++ protobuf::libprotobuf silkinterfaces silkworm_core silkworm_node mimalloc)

and running it using Apple clang version 13.0.0 (clang-1300.0.29.30)

Sorry I forgot to mention that this is the line giving me the error https://github.com/Thalhammer/jwt-cpp/blob/5c588fccd67545b5bbe1d7653963034d0151742a/include/jwt-cpp/traits/danielaparker-jsoncons/traits.h#L6

[prince-chrismc]

Hmm I don't see the exact error you described in the pull request but it gives me a better idea of what you are trying to do!

Since we only have default settings, only the examples might be bringing the bad include...

For a test, you can try setting https://github.com/Thalhammer/jwt-cpp/blob/5c588fccd67545b5bbe1d7653963034d0151742a/CMakeLists.txt#L14 To OFF right before add submodule

Should look like (on mobile incase I make a typo)

set(JWT_BUILD_EXAMPLES OFF CACHE BOOL "disable examples" FORCE)

Also I see this project have hunter support which this project supports so we can go that road if we get stuck.

[enriavil1]

The thing is that it doesn't get to that point. It fails building the folder jwt-cpp/include also the problem with hunter is that it says this "Could NOT find jsoncons (missing: jsoncons_DIR)"

[enriavil1]

I just tried it turning off examples, but it didn't work

[prince-chrismc]

Your project is really interesting! 🎉

So I cloned your branch and tried to play around but the code did not match what you shared, so I am not really sure what the issue you are facing. It's hard to help without the code to trying things out.

It seems like a project specific issue so I am going to close this, but if you find anything do not hesitate to re-open.

It's a pretty complicated build script so if you need help I love pair programing feel free to reach out.

[enriavil1]

When you ran cmake --build . it didn't give the same error?

[enriavil1]

I'll keep looking into it, but I believe the real culprit is Hunter not finding the "jsoncons" package.

[prince-chrismc]

I got the same errors as the pr when I looked, I share your suspicious around hunter. I recall it flips the default Cmake settings to be more sensitive but I don't have a lot of experience with it
